Can simply 3 cylinders actually energy a contemporary crossover?
Automobile customers with an curiosity in what’s occurring below the hoods of recent vehicles and crossovers possible have a really feel for contemporary engine configurations. Hottest crossovers are powered by turbocharged 4-cylinder engines, or larger-displacement V6s.

What’s a 3-Cylinder Engine?
Are extra cylinders higher?
The 2025 Jeep Wrangler, for instance, is obtainable with each a turbocharged 2.0-liter for, or a usually aspirated (not turbocharged) 3.6-liter V6. (The Wrangler can also be accessible with a limited-edition V8.)
And whereas V8 engines have change into uncommon—at the very least in reasonably priced autos—small turbocharged engines have change into rising in style, most of that are of the 4-cylinder selection.
4-cylinder engines
Individuals as soon as shunned 4-cylinder engines, apprehensive that they wouldn’t have the ability to speed up onto the freeway, or safely carry out a passing maneuver. However years of improvement have helped carmakers produce potent and environment friendly small engines that rival the ability of V6 and V8 powerplants of solely a decade or so in the past.
3-cylinder engines
However know-how continues to advance, and automakers proceed to develop smaller and extra fuel-efficient engines, principally to be used of their smallest and most-affordable choices. One such development is the 3-cylinder engine.
Widespread in Japan
Now, 3-cylinder engines should not new–they’ve seen use in non-automotive purposes for years, and might be discovered is vehicles and vehicles in markets together with Japan—however they’ve been largely absent from the U.S. market.
Autos with 3-cylinder engines
However the quest for gasoline economic system–and decrease manufacturing prices–has introduced the 3-cylinder to American customers, and it’s accessible in a shocking variety of autos. Right here’s an inventory of 2025 fashions accessible with a 3-cylinder engine:
Buick Envista (137-horsepower 1.2L)
Buick Encore (137-horsepower 1.2L, 155-horsepower 1.3L)
Chevrolet Trax (137-horsepower 1.2L)
Chevrolet Trailblazer (137-horsepower 1.2L, 155-horsepower 1.3L)
Ford Escape (181-horsepower 1.5L)
Ford Bronco Sport (181-horsepower 1.5L)
Mini Cooper (156-horsepower 1.5L)
Mini Cooper Convertible (156-horsepower 1.5L)
Nissan Rogue (201-horsepower 1.5L)
Toyota GR Corolla (300-horsepower 1.6L)
3-cylinder engines: Execs and Cons
However what are the drawbacks of proudly owning a automobile with a 3-cylinder engine? Will it’s much less dependable than a 4-cylinder engine? Will it have the ability to maneuver a automobile with applicable gusto? A pair ideas:
Execs: Benefits of a 3-cylinder Engine
- Lowers value of auto manufacturing, which can assist decrease sticker costs
- Ought to ship higher gasoline economic system than comparable 4-cylinder-powered autos (hybrids excluded)
- Could value much less to take care of
Cons: Draw back of a 3-cyliner engine
- Can really feel tough at idle
- Could not sound refined or sporty throughout acceleration
- Usually much less highly effective than turbocharged 4-cylinder engines
Idle quake
The rationale that 3-cylinder engines are much less clean in operation than most different engine configurations is the odd cylinder depend. In a contemporary gasoline engine, every cylinder fires (actually explodes) as soon as each different rotation of the engine’s crankshaft. So, in a 4-cylinder engine, two cylinders fireplace every rotation of the crank, in a 6-cylinder engine three cylinders fireplace…and so forth.
Nevertheless, in a 3-cylinder engine, one cylinder fires one rotation, whereas two fireplace the subsequent rotation. Due to this uneven sample, 3-cylinder engines can really feel much less clean at idle, and through acceleration. This inherent quake can be felt in 5-cylinder engines, which have been as soon as generally present in Volvo autos.
All this mentioned, we’ve not discovered 3-cylinder-engine-powered check autos to be particularly unrefined, just a bit much less refined than comparable 4-cylinder fashions.
Shopper Information has evaluated plenty of automobile geared up with 3-cylinder engines, and we’ve discovered all of them at the very least ample by way of efficiency. Additionally, our noticed gasoline economic system has been wonderful. We advocate you learn our evaluations of the next autos, listening to our findings relating to energy and gasoline effectivity.
CG Says:
Is a 3-cylinder engine best for you? In all probability, except you’re particularly delicate to drivetrain refinement quirks. Be sure you fastidiously check drive any automobile you’re contemplating buying, and make sure you pay particular consideration to engine noise and vibration. That mentioned, we at Shopper Information don’t have any explicit reservations relating to the acquisition of a automobile geared up with a 3-cylinder engine.
